Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of AGV automatic running vehicles, in particular to an AGV automatic running vehicle for medical supplies. BACKGROUND

[0002] In the modern medical system, efficient and safe transfer of medical supplies is of great importance. AGV automatic running vehicles have been widely used in the transfer of medical supplies due to their automation and flexibility, etc. for transferring large-volume medical supplies, such as the patent announcement No. CN212291498U AGV intelligent identification running vehicle based on RFID, which comprises a vehicle body base, a vehicle-mounted storage rack and a gantry type linear module are arranged on the vehicle body base, the gantry linear module comprises two Z-direction synchronous belt linear modules, a rotating shaft, a first motor, and two couplings; the two Z-direction synchronous belt linear modules are vertically fixed on the vehicle body base, the rotating shaft is connected with the top of the two Z-direction synchronous belt linear modules through the couplings at both ends, and the first motor is arranged at one end of the rotating shaft; a first sliding block is arranged on the Z-direction synchronous belt linear module; a Y-direction synchronous belt linear module is connected with the Z-direction synchronous belt linear module through the first sliding block; a second sliding block is arranged on the Y-direction synchronous belt linear module, and a second motor is arranged on one end of the Y-direction synchronous belt linear module.

[0003] However, the above-mentioned AGV vehicle directly extracts the medical supplies for transfer, which exposes the medical supplies completely. For those medical supplies with strict temperature requirements, especially those that need to be kept at low temperature, the low temperature will continuously spread out during the transfer process. For example, some biological agents, vaccines, etc. need to be stored in a specific low-temperature environment to maintain their activity and quality. However, the existing transfer method causes the temperature to gradually rise, and once it exceeds the specified temperature range, the performance of these medical supplies will be affected, and even lose their effectiveness, which not only causes waste of resources, but also may have serious consequences for medical treatment. In order to minimize the impact of temperature rise, the existing AGV vehicle can only speed up the transfer speed, but this puts higher requirements on the transfer efficiency and stability, increasing the difficulty of transfer. Therefore, the present application designs an AGV automatic running vehicle for medical supplies to delay the temperature rise of medical supplies and ensure stable transfer of the AGV vehicle.

[0041] The driving motor 305 drives the driving rotating wheel 306 through the gear box 304 to rotate, and the four universal wheels 303 are used to move the placement platform 1, thereby meeting the transfer requirements of the materials. The driving rotating wheel 306 is arranged on both sides, and the driving direction and speed of the two driving motors 305 are controlled to adjust the angle of the placement platform 1, so that the application can rotate by the speed difference and the driving direction between the two driving rotating wheels 306, thereby meeting the transfer requirements in any direction.

[0045] By starting the right-angle deceleration motor 4075 to drive the transmission gear 4074 to rotate, under the meshing of the synchronous gear 4071 and the transmission gear 4074, the synchronous gear 4071 rotates and drives the three driven gears 4073 to rotate the three rotating lead screws 4072 in the movable plate 407, under the rotation of the rotating lead screw 4072, the rotating lead screw 4072 and the cooperating screw sleeve 4081 are threadedly connected, thereby driving the movable plate 407 to move up and down to adjust the height, so that the support tray 402 of the application moves to the lower side of the material support, and then the right-angle deceleration motor 4075 is started to make the support tray 402 rise, so that the material is automatically lifted to the upper side, realizing the rapid storage of the material. Similarly, the right-angle deceleration motor 4075 rotates in reverse to make the support tray 402 descend, so that the material rack falls to the ground and the application is separated from the material, realizing the rapid unloading of the material. Through the above structure, the application can automatically load and unload the material, reduce personnel intervention, reduce the workload of personnel, and improve the efficiency of loading and unloading the material.

The second visual sensor 404 can identify whether the material is loaded above the support tray 402 and whether the material is separated from the support tray 402, so as to control the start and stop of the right-angle deceleration motor 4075.

[0048] The lifting assembly 4 can automatically load and unload the medical material, thereby reducing the direct contact between personnel and the application, not only reducing the working intensity of the operator, but also reducing the contact pollution probability between the material and the personnel, and can actively cool the medical material, which can further delay the temperature rise of the material, which is beneficial to the automatic transfer of the medical material.

[0049] In the application, the protection assembly 5 comprises a bearing seat 501 fixedly installed on the upper surface of the installation platform 1, a turnover shaft 502 rotatably installed in the bearing seat 501, a storage seat 5021 rotatably arranged on the shaft body of the turnover shaft 502, a flexible film roll 5022 placed in the storage seat 5021, a turnover rod 503 installed at both ends of the turnover shaft 502, a butt joint frame 505 fixedly installed at one end of the turnover rod 503, and a winding shaft 5052 installed between the two butt joint frames 505. The turnover rod 503 is arranged at a vertical angle before loading and is turned to a horizontal angle after loading.

[0050] It should be noted that the hollow shaft motor 5023 is fixedly installed outside one side of the bearing seat 501, the output shaft of the hollow shaft motor 5023 is fixedly connected with the shaft body of the turnover shaft 502, the pressing baffle 504 is rotatably installed on the rod body of the turnover rod 503, the torsional spring 5031 is installed at both ends of the rod body of the turnover rod 503 and connected with both ends of the pressing baffle 504, the winding motor 5051 is fixedly installed outside one side of the butt joint frame 505, and the output end of the winding motor 5051 is fixedly connected with the winding shaft 5052.

[0052] The hollow shaft motor 5023 is started to drive the turnover shaft 502 to rotate in the bearing seat 501, and the two turnover rods 503 are turned during the rotation of the bearing seat 501. The end of the flexible film roll 5022 is fixed in the winding shaft 5052 during the turning of the turnover rod 503, so that the flexible film roll 5022 is extracted and turned to cover the current materials, so that the flexible film roll 5022 covers the materials to isolate them from the outside world, reduces the contact between the materials and the outside world during the transfer, further improves the stability of the materials during the transfer, and automatically operates through the above structure to improve the transfer quality without additional personnel operation;

[0053] It should be noted that the two ends of the flexible film roll 5022 are connected with the storage seat 5021 and the winding shaft 5052 respectively. During the turning process, the turning of the winding shaft 5052 will pull one end of the flexible film roll 5022, so that the flexible film roll 5022 will turn to one side, and with the continuous turning, the flexible film roll 5022 will wrap around the goods from above until the winding shaft 5052 turns to the other end, realizing the wrapping of the flexible film roll 5022 on the goods. The above-mentioned turning drive makes the flexible film roll 5022 be stretched out and turned to cover the current goods to realize auxiliary isolation.

[0054] Wherein by starting the winding motor 5051 can winding flexible film roll 5022, the old flexible film roll 5022 is wound to be discarded directly in later period, not only makes the flexible film roll 5022 can be straightened to cover goods and also makes the used flexible film roll 5022 will be wound into the winding shaft 5052 after taking out the goods, so that the new flexible film roll 5022 is extracted when the new goods is transported, avoiding the pollution of the material after use. The material of the flexible film roll 5022 can be used according to the specific goods, generally using antibacterial heat preservation film, solving the problem of cross contamination with the outside during the transportation of goods.

[0057] The torsional spring 5031 is arranged between the pressing baffle 504 and the turning rod 503, so that the placing angle of the pressing baffle 504 is downward by default. The pressing baffle 504 can press the two sides of the flexible film roll 5022, so that the two sides of the flexible film roll 5022 after covering the goods will not be automatically opened, thereby ensuring the stability of the flexible film roll 5022 when covering the goods.

[0058] Wherein the air is filtered through the air filter 508, start the air inlet fan 507 to transport air to the connecting hose 5044, under the action of auxiliary impeller 5043 and air outlet cavity 5042, air from the gap in a uniform, stable laminar flow state downward, forming a vertical downward sterile air curtain wall, auxiliary isolation operation on the lower side of the flexible film roll 5022, can effectively prevent the external air pollutants into the internal material.
